This Mysterious Pond is almost identical to the one found within the Waterfall of Wishing. If Link tosses an item in, the Cursed Fairy appears, asking if Link threw the item in. Specific items thrown into the pond could cause Link to acquire a few upgrades. Most notably, if Link tosses in his Bow and Arrow and admits to doing so, the Cursed Fairy rewards his honesty with the Silver Arrows. These special arrows are needed to deal the final blow to Ganon.

If Link has acquired the Tempered Sword, he can toss it into the Mysterious Pond. If Link acknowledges that he threw it in, the Cursed Fairy upgrades the Sword to the ever-so-powerful Golden Sword.

Link can also throw in an empty Magic Bottle. If Link acknowledges that he threw it in, the Cursed Fairy returns the bottle filled with Green Potion.
